HINGE POR A DOOR OR VUJIIN'I)Q'WQIRABEv .OF A'STQVE.

l The Schedule xel'en'ed tain these Letten Patent und maklngpaxt of-'thesame.

To all whom it may concern Be it known that I, THOMAS J'. OOULsToN, ofSpringville, vin the county of Ohester, in the State of of the saine,reference'being had to the accompany- .ingdrawings making-a pjart ofthis specification, in

which- Figure 1 is a perspective View of an open whdowframe or door,attached to the plateof a1 stove by means-of the said 'hingej wFigure 2,.a yertical central section of iig. 1; and

Figure 3, a like section of the same parts, showing the said frameclosed and fastened.

Like letters andnumbers of reference indicate the same parts when in thedifferent figures.

The natureof my Vinvention consists in the cnnstruction of a, moresimple, cheap, and reliable concealed hngefor .the mica-panelled doorsand windowframes of stoves, substantially as hereinafter set forth anddescribed. y l

Referring to thedrawingsm A is a r'nicafpanelled door or window-frame ofa magazine-stove;

B, o'ne of the open. plates of the stove, to which the frame A isattached; and

' a' b', the hinge, whereby the Vtwo said partsare coupled together.

The frame A consists of two parts, the exterioror ornamented part a",and `the interior part a'", which are adjustably secured together, bymeans of studs andpins 4 4, for the purpose of securing the usualsheetof mica between them.

The plate B is cast with an opening, b", correspond-- ing in its generalform and position with, but some-v what less in' size than the externalor ornamented part a, ofthe frame A.

The lower boundary of the opening b of the plate B is cast with anoblong rectangular recess, b', and

' two lugs, b" b', which, together, form one-half part of the hinge.

The otherhalf of the hinge is cast simultaneously with, and forms partof the exterioror ornamented part-a of the frame A, and consists of. adownward projection, a', having an angular recess, 5, (see fig. 1,-) ine'ach side, which allows it to tit readily in the recess b belowthe'lugs b' l', while the two lugs C C, which.

are left by the notches or recesses 5 5, project behind the plate B, andthus serve, in combination with the lower part ofthe exterior fraine aand the lower part of the outside of plate B, to support the door orwindow-frame A in the horizontal or open position shown in figs. 1 and2, and also allow the said frame A to be readily tuilled upward thereon,as on a hinge, in closing they frame A against the plate B, and keepingit steadily in that closed posit-ion, as represented in Projectingon theinner side of the upper end of the part a' are two notched or under-cutstuds, 7 7, which will vpass through the two respective recesses 8 8, in

-the1upper part-of the plate B, if theframe A be slipped upward a shortdistance, in closing it against the said plate B, and will then catchbehind the respective side edges 9 9 of the` latter, on slipping thesaid frame A downward to its original position, thus fastening the saidframe A in place over the opening` b" in the plate B, and at 'the sainetime covering the open recess b', or concealing the hinge.

It will therefore be seen thatthis hinge alords ready'facility inopening andclosing vthe frame A, for the introduction of fuel, and forcleaningand keeping .clear the mica; that, when closed, the hinge isconcealed, or covered, so as to be invisible; and that the i two partsa. b', being cast in their respect-ive plates,

A B, andv not requiring anything more than the simply adjusting themtogether to complete the hinge, it

can be made and applied almost without any special cost,.and willalsoserve the purpose intended, in the most perfectand reliable manner.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

A hinge', a' b', constructed, applied, and operating substantially inthe manner and for the .purpose described.

THOS. J. -COULSTON.
